WEATHER-GUARD FOR WINDOWS.

To all whom it may concern:

Be it known that we, IVILLIAM S. HAMM and ALFRED H. NEWPHER, citizens ofthe United States, and residents, respectively, of Hubbard Woods, countyof Cook, and State of Illinois, and Chicago, county of Cook, and Stateof Illinois, have invented certain new and useful Improvements inVVeather-Guards for Windows, of which the following is a specification,and which are illustrated'in the accompanying drawings, forming a partthereof.

The invention relates to Weather guards for windows, and is for use onthe side rails of a sliding sash; its object is to secure an air tightjoint without material friction tending to retard the movement of thesash.

A further object is to provide a construction which will have greatdurability and be permanently reliable.

The invention is fully hereinafter described, and is illustrated in theaccompanying drawings, in which Figure 1 is a detail section and partlybro zen away, of awindow casing and sash mounted therein; Fig.

7 2 is a longitudinal section of the guard;

and Fig. 3 is a detail cross-section on the line 3-3 of Fig. 2. In thedrawings the invention is shown in connection with a windowespeciallyadapted for car construction, and there is represented at 10 aportion of the outer wall of a car body and consisting of a metal plate;at 11 is shown a window sill; at 12 one of the stiles of the windowcasing and having an adjustable stile plate 13 and sash stops or guides14, 15 and 16; at 17, 18, are shown a pair of sash fitted within thesashways bounded by the stops. While two sashes, an outer and an innerone, are shown, the invention is equally applicable to a single sashwindow.

An angle plate 19 is secured by means of screws, as 20, 21 and 22,to theouter face of the side of the car. As shown, the stile 12 is providedwith a flange 23, which is folded back on. the outer face of the wallplate 10; and the outer leaf of the angle plate 19 is fitted directlyupon this flange, its edge overlapping the same and being turned inwardto meet the plate 10 for the purpose of forming a tight joint therewith.The instanding Specification of Letters Patent.

particularly adapted erspective, partly in Patented June 11, 1912.Serial No. 618,727.

leaf 2 1 of the plate 19 makes a loose con- .tact with the outer sash17, and is spaced apart from the outer stop 14, forming there- 'with achamber having an open side directed toward the sash. Within the chamber'thus formed there is housed a longitudinal plate 27 hearing against theinwardly fold-- ed portion of the plate 26 and the free edge 29 of thelatter plate being adapted to'bear against the outer face of the sash17. To prevent wear the side rail of the sash, when of wood as shown, ispreferably covered with metal, as at 30.

A spring, as 31, is applied to the back or outer face of the bar 25, andreacts against the outer wall of the plate 19 for the purpose of urgingthe bar and the plates carried thereby toward the sash. The plates 26,27, may be formed of a single sheet folded about the bar 25, and may beconveniently secured thereto by means of screws, such as 32, of anydesired number, one of which is shown, and as serving also to attach thespring 31 to the bar. The spring 31 presses the bar 25 toward the sashwith suflicient force to insure a slight flexure of the inwardly foldedflange of the plate 26, thus causing it to make a tight joint with theflange 28 of the plate 27 and a tight joint with the sash by theengagement therewith of its edge 29. We have found that by this openside facing the sash-way, a floating bar.

within the casing, a pair of flexible plates carried by the bar andfolded to overlap,

one of said plates having its free edge presented to the sash-way andadapted to engage a sash, and a spring urging the bar toward thesash-Way.

2. In a weather guard for WlIldOWS, in combination, a stile having alongitudinal chambered casing, such chamber having an open side facingthe sash-Way, a floating bar u'ithin the casing, two flexible plates ofspring metal attached to the bar and projecting from opposite sidesthereof toward vthe sash-Way, such plates having'their free
